The u/s results showed an enlarged thyroid and 5 small nodules (the largest one measuring 33mm).

The doc (who is not an endo) just told me to take B12 supplements and come back for a blood draw (for the B12) in three weeks.
Why did he even run the B12 and folate?
What do you think of my thyroid results?

These folks can't get it together can they? Is that Free T4? You are pretty close to bottom of range. I'm guessing you meant to say they did not run the Free T3? It is not normally on the standard form as a box you can check, usually has to be written in.

And your B12 is rock bottom! My doc recommends injections for anything under 800. Are you having tingly limbs??? If I were you I would be sure to get the sublingual B12 @ 5000 MG.

I've read the sublingual type is absorded into your body better than the regular tablets. And if you do get 1,000 mcg I'd start taking two or three a day to get your numbers up. This is why your hands are tingly. I've not heard of a correlation between B12 and BP but it did also clear up an issue I was having with my eyesight. And I never had a problem with BP until I became hypo, and then it skyrocketed. Was fine after a few months on thyroid meds and now that my numbers are out of whack again, my BP is up again.
